Letters Patent No. 98,118, dated December 21, 1869.

IMPRdVEfl GAS-GENERATOR AND 'CARBURETTBR.

0- -o. The schefiulerrefured to ii: these Letters Patent and making part offlae lame.

To all whom it may concern Be it kn'own um I, AMos scmvsss, of- Fitchburg;

in theconnty of Worcester, andSt-ate of Massachusetts, have invented Improvements inglpparatus for Generating andGa rburetting lllnmii'iating-Gas; and I do hereby dcelarethat the following, taken in connection with the drawings, which accompany and form part of this specification, is a description of my invention suflicient to enable those skilled'in the art to,

practice it.

' The above drawings represent a hydrogen-gas generator and carburetter. I,

A, the outside cylinder, witha bottom B, set up in the cylinder six inches.

U is another cylinder, connected with the bottom "B, forming the tank 1).

The cylinder 0 is of proper size to form alspace of about six inches between it and the outside eylinder A.

In this space is an oil-tank, formed of two cylinders 11 and F, connected with bottom B.

These cylinders, E and F, are three inches apart,

and coiered'wit-h a top, G. v

Thespace between-the cylinder A and O is filled with water up to the dotted line H.

The water covers and surrounds the oil-tank I.

In this space of water are two more cylinders, J. and- K, which are connected with the top L, which is free to rise or fall, accordingto the pressure of gas.

The tank D is filled wit to'escape when the vessel is raised.

The top L-is fitted with a screw-cap, N, through which the solution is passed to the tank I), as is also the zinc or iron, to the vessel M.

The pipe 0 conveys the hydrogen from the generator, downthrough aspace or pun designed to'receive the drip.

In this space the pipe is disconnected, to allow the drip to escape.

From this space the gas is taken out through the pipe 1, that passes to the top of the oil-tank,then turning down to the bottom, is perforated with numerous small holes, and lies coiled once around on the bottom of the oil-tank.

R shows a sect-ion ofthe perforated pipe.

solution of sulphuric. acid and water up to the' d te'tiline, in which is' T, and conveycd'to me drip-pan V.

From this pan it is taken out through the pipe W,

and conveyed tothe burners; X is a draw-ofl' for water.

Y, a dl'aw-oiffor the drip'fronr-pcn.

Z, a draw-0d for 'soiution.

U, a draw-oft for oil.

In thetop of this drawsofi' .pipeis inserted a tube, rising perpendicular to cap 5. Through this cap' and tube the oil is filled to the tank I.

To put the machine in operation, the tank is filled with the solution up to the dotted line, .and a quantity of zinc or iron put into the vessel M, when gas. is at once found passing through the pipes, as above described, and the top L is raised, by the pressure of the gas,'to the position'of the dotted line, and the vessel M is raised out of .the solution, and the action ceases.

'In'this position. the machine will remain till theburnersar'e lighted, which takes off the pressure, and-- diameters, two connected with the bottom B, and two with the top L, for the purpose above described.

2. The position 'and form of the oil-tank I, being formed of two cylimlers,.with the top G, and being placed in the centre of the space of water, is completely covered aml-surrounded by it, substantially as and for the purpose hereinbet'ore set forth.

3. Passing the gas up through the water, by means of the perforated pipe S, substantially as and for the purpose hercinbei'ore described-and set forth.
